Going through rustlings for the first time
1// `Vec<T>` is generic over the type `T`. In most cases, the compiler is able to
2// infer `T`, for example after pushing a value with a concrete type to the vector.
3// But in this exercise, the compiler needs some help through a type annotation.

5fn main() {
6 // TODO: Fix the compiler error by annotating the type of the vector
7 // `Vec<T>`. Choose `T` as some integer type that can be created from
8 // `u8` and `i8`.

12 let n1: u8 = 42;
13 numbers.push(n1.into());
14 let n2: i8 = -1;
15 numbers.push(n2.into());
